Activités de recherche et d'enseignement
Enseignant-chercheur dans le domaine des réalités étendues, mes recherches portent principalement sur les personnages virtuels (avatars/agents) et la collaboration dans des environnements immersifs. J'étudie le sentiment d'incarnation et ses corrélats cognitifs et comportementaux. Coresponsable du master MTI3D de l’institut Arts et Métiers de Laval, je forme les étudiants à la recherche expérimentale et j’y enseigne l’infographie, le rendu 3D temps réel et la programmation pour les interfaces de réalité virtuelle.

The proportion of the population who experience persecutory thoughts is 10–15%. People then engage in safety-seeking behaviours, typically avoiding social interactions, which prevents disconfirmatory experiences and hence paranoia persists. Here we show that persecutory thoughts can be reduced if pr…
